Electrical Engineering:
Electrical Engineering is the broad discipline that deals with design, development, and maintenance of electrical systems including circuits, power systems and electronics, and signal processing. The main goal is to design electrical systems that are reliable, efficient, safe, and meet performance specifications.
Key Focus Areas Include:
Digital Logic and Circuit Design: logic gates and processors
Signal Processing via filtering, amplification and analog conversion
Power Systems e.g., battery managejment and voltage regulation
Electronics and Semiconductors e.g, tranistors and integrated circuits
Control Systems
Communications and Data Transmission
Biomedical Engineering:
Biomedical engineering is an interdisciplinary field combining engineering principles with biological and medical sciences to design and create equipment, devices and systems for health care applications. The main goal is to improve healthcare outcomes through innovative engineering solutions that are safe, effective, and meet medical regulatory requirements.
Key focus areas include:
Medical device design and development
Biosignal processing (e.g., ECG, EEG, blood pressure monitoring)
Biomaterials and biocompatibility
Medical imaging systems
Regulatory compliance and safety standards
Human factors and patient interface design
Both Disciplines in Context of Patient Monitoring System
Developing a cardiac patient monitoring system is multi-discipline process that involves both electrical engineering and biomedical engineerin. Electrical engineers will be responsible for desigining the digital logic circuits, power management systems and signal processing components that convert biological signals into digital data (electrical signals). This includes create the 555 tyimer cicruits for system timing like how we did or implmenting AND/ OR logic gates for decision making. Biomedical Engineers are responsible for ensuring the device meets the medical safety standards, is biocompatible with patient contact, and properly interprets physiological signals such as troponin levels, ECG data and Sp02 measurements similar to what we were given in our Patient Monitoring Guidelines. All of the above disciplines will provide assurance that the patient monitoring system is technically correct, medicallt effective and complies with regulations.
